I'd have to say that as much as we saw of Valero, Manny would have beaten him every night of the week. That's not to say that Valero could not have improved enough to have got a win over Manny a couple of years down the line.

It's a shame we will never know. Valero had devastating power and was a very intense fighter but to me he appeared very raw and Manny would have had too much skill, he is a more complete and refined fighter.

Would have been good to see definitely though. Look at how Mannys career turned out after 2 early career ko's and a draw more than a decade ago. (although killing himself to make weight had a bit to do with being ko'd for me)

Valero definitely had the potential to to reach the level required.
